AGENDA ITEM 7K • STAFF ORIGINATOR: John Powell, City Engineer • COUNCIL MEETING DATE: March 12, 2001 TOPIC: Resolution No. 01 -43, Order the Preparation of Plans and Specifications for the Black Duck Lift Station VOTE REQUIRED: 3/5 Vote Required BACKGROUND: The existing Black Duck Lift Station is located on the west side of Black Duck Drive, south of Lantern Lane. A new lift station is proposed to replace the existing lift station which was constructed in 1970. In 1994, the City prepared plans and specifications to construct a new lift station and rejected the bids due to the high contract prices received. The City also initiated a project in 1998 to replace this lift station but terminated the process due again to estimated costs. The waste water flow volumes that enter the existing lift station have continually increased and the lift station needs to be replaced in order to operate in a safe and efficient manner consistent with current design standards. The pumps in the station have to operate much more frequently each hour than desired. The station also has very little storage which causes the sanitary sewer to be surcharged. As with the earlier project, staff is proposing to construct a new lift station consisting of a wet well and submersible pumps on the east side of Black Duck Drive within the unimproved Captains Place right -of -way. This will allow the existing lift station to remain in service as the new one is constructed. The new design will also eliminate the pump house as all of the components of the new lift station will be underground except for a control panel and a generator shelter. The cost of replacing this station will continue to increase. The cost of maintaining the station will also continue to increase as the components wear out more quickly due to high cycling frequencies. Replacing the station with a submersible pump system will also reduce OSHA confined space entry by City Public Works personnel. The funding for the project is proposed to come out of the City's Trunk Area and Unit funds. It is this type of project for which the Area and Unit funds were specifically created. OPTIONS: 1. Return to staff for further review. 2. Adopt Resolution No. 01 -43 Order the Preparation of Plans and Specifications for the Black Duck Lift Station project. • RECOMMENDATION: Option No. 2 - Adopt Resolution No. 01 -43 Order the Preparation of Plans and Specifications for the Black Duck Lift Station project
